l lTmlm sin-is RADIATI'NG-DRUM.

To all whom it may concern:

Be it known that I, RIoIIA'RD MARX, a citizen of the United States of America, residing at Detroit, in the county of WVayne and State of Michigan, have invented certain new and useful Improvements in Radiating- Drums, of which the following is a specification, reference being had therein to the accompanying drawings. I

This invention relates to a radiating drum, and the objects of my invention are to provide positive and reliable means, in a manner as hereinafter set forth, for baflling and retarding products of combustion, hot air and the heated gases, whereby heating units can be derived from the products of combustion before their final escape to an exhaust flue or chimney, and to provide a radiating drum with detachable baffles that can be easily and quickly removed whereby the battles and the interior of the drum can be cleansed of soot and other foreign matter that may accumulatetherein.

Further objects of my invention are to provide a radiating drum with a sinuous or tortuous path for products of combustion which are carried against the walls or periphery of the drum to heat the same, and to accomplish the above results by a simple, durable and inexpensive chimney or flue drum that permits of a high degree of heat being obtained by a minimum expenditure of fuel.

The above are a few of the objects attained by the novel construction, combination and arrangement of parts hereinafter specifically described and then claimed, and reference will now be had to the drawings, wherein Figure l is a front elevation of the radiating. drum; Fig. 2 is a plan of the same with the cover thereof removed; Fig. 3 is a perspective view of the drum partly broken away; Fig. 4 is a perspective view of the superimposed baffle; and Fig. 5 is a perspective view of a detached bottom baffle.

A radiating drum in accordance with this invention comprises a fixed circular head 1 carried by the lower end of a cylinder or cylindrical shell 2 which has the upper end thereof provided with a detachable circular head or cover 3. The heads 1 and 3 are provided with concentric openings for sleeves 4:. These sleeves permit of the radiating drum being easily and quickly installed in connec- Specification of Letters Patent.

" with a stove pipe or the exhaust conduit of a heating apparatus.

A side of the cylinder or cylindrical shell 2 has an opening normally closed by a hinged door 5. This door permits of easy access being had to the interior of the cylinder for removing soot or other foreign matter.

Within the cylinder 2 and resting upon the head 1 are the legs 6 of a bottom baffle 7, said bafiie being triangular in plan and in spaced relation to the header 1. Centrally of the bottom balile 7 is a support 8 riveted or otherwise connected to the baffle. This support cooperates with other supports 9 in spacing and holding a plurality of superimposed baffles 10 within the cylinder 2. The baffles 10 are triangular in plan, similar to the bottom baflle 7 and in placing the baffles in position, the radiating portions of one baffle are staggered relative to the radiating portions of other baflies, thereby providing a sinuous or tortuous passage from the bottom of the cylinder 2 to the top thereof. Products of combustion caused to travel in the sinuous passage of the cylinder contact with the walls or periphery of the cylinder thus heating the same and air surrounding the cylinder.

All ofthe baflles can be easily and quickly placed in position by simply removing the upper header or cover 3, and with the device in its entirety made of light and durable sheet metal, the entire device is thoroughly heated before the escape of products of combustion orheated gases from the top of the drum.

I attach considerable importance to the simplicity of construction, as the drum can be manufactured at a comparatively small cost, thus permitting of its installation in connection with a low grade of stove, whereby a maximum of amount of air can be heated at a minimum expenditure of fuel.

One embodiment of my invention has been. illustrated, but it is to be understood that the structural elements are susceptible to such variations and modifications as fall tom baflle having integral legs supported by one of said heads, superimposed fiat baffles above said bottom baffle, supports connect- In testimony whereof I aflix my signature ing said bafl les centrally of said cylinderand in presence of tWo Witnesses. all of said baiiles being triangular in plan RICHARD MARX with radiating portions of one baflie staggel-ed relative to radiating portions of other WVitnesses:
